Velocity at ground v u 2gH 1 Time taken to reach the ground H ut gt This is a quadratic equation that can be solved by factorisation or using quadratic formula to calculate time Let three balls 1 2 and 3 are allowed to fall under gravity from the same height Ball 1 is thrown vertically upward with speed u and it reaches the ground in time t Ball 2 is thrown vertically downward with the same 0 speed u and it reaches the ground in time t Ball 3 is dropped i e u from the same height and it reaches ground in time t Then the relationship between t t and t is given by Downward motion of object t Upward motion of sound t ALLEN H t3 t t An object is dropped in a well of depth d and the sound of splash in water is heard after a certain time T 2d g d 2 u 0 143 the equation to calculate time taken to re ch the ground why is initial velocity taken a
